Serial No.l 319,837.

The primary ob]ect of my invention is to provide an improved vconstruction and arrangement of parts in a machine of this character whereby caps may be rapidly se arated from the bottom of a cap-holding opper, positively controlled during their movements into cap-applying position with vrespect to successlvely-presented bottles and accurately applied to said bottles.

Another object of my invention is to provide a cap-feeding slide o'f improved construction wherein a suction gripper is em-- ployed for effectively controlling a cap while it is being separated from bulk preparatory l to its movement into cap-applying position under the positive control of said slide.

Other objects of my invention will appear in the specification, the particular features of construction appertaining thereto being recited in the claims in reference to the accompanying drawings which show a preferred embodiment of my invention.

igure 10 is a vertical medial section through the left hand portion of Figure 9. Figure 11 is an enlarged section on the line 11-11 of Figure 1.

Figure 12 isa section similar to Fi with the parts shown in changed positlons.

Figure 13is an enlarged horizontal section corresponding to the line 13-13 of Figure 1.

Figure 14 is an enlarged horizontal section corresponding to the line 14-14 of Figure 1. Referring more particularly to the drawlngs, laterally spaced uprights 1 and 2 serve to mount a cross frame or bracket 3 which isV secured to said uprights by means of set screws 4. As shown in Figure 5, the cross frame'3 is provided with two sets of oppositely arranged guideways or grooves 5 with- 1n which are reciprocably mounted crosshead slides 6 which are provided'with oppositely presented track bars 7 which reciprocate in the grooves 5. Each of the cross-heads is connected by a web or neck 8 to a tubular hopper 9 which'is provided with an enlarged block or foot l0, as shown in Figures 6 and'8. Said block or foot is secured to a feed table 13 by means of screws 12 which pass through a base flange 11 of said block or foot and are threaded into said feed table. Each feed table is movable vertically in the manner to be hereinafter pointed out and is provided with an opening 14 for accommodating the neck of a bottle presented to receive a cap.

The lower limit of movement of the table 13 is determined by a transverse bracket 15 which is secured to the uprights 1 and 2 by means of set screws 16. As shown in Figure 6, the table 13 is provided with a tubular connection 17 through which extends a portopening 18, the connection 17 being connected to a vacuum tube 19 to adapt the table to yieldably retain a cap above the port-opening 18. The table 13 is provided with a rearwardly presented extension 2O which is reinforced by longitudinal ribs 21, as shown in Figures 4 and 6. Reciprocably mounted upon the table 13 lis a` slide 22'which, as shown best inFigures 1, 4 and`7, is provided with a forwardly resented abutment 23 adapted to limit the orward movement of said slide when it is brought into engagement. with a shoulder or abutment 24 which is presented downwardly from the extension 20. Suitable means for limiting the rearward movement of the slide 20 may be provided by. a fixed stop or flange 25. The cap feeding slide isprovided with a top plate 26 which, as shown` in Figure 5, is provided with an arcuate recess 27. lSecured to the top plate 26 is a suction platev 29 which-is held in position by screws 30 and provided with a suction port-opening 31 which is adapted during the forward movement of the slide to be brought into communication with the portopening 18 leading to suction pipe 19. Presented forwardly rom'the slide 22 are laterally spaced cap controlling fingers 32 which during the forward movement of the slide are adapted to project over the circular flange of a cap which is being moved forwardly into cap-applying position. Arranged below the fingers 32 and projecting from the forward end of slide 22 are laterally spacedy cap supporting. pins 33 which, as shown in Figure l0, are adapted to pass beneath thecircular flange of the forwardly dis laced cap.

eferring more especially to Figure 3, the slide 22 has laterallypresented portions 34 which are provided with upwardly presented slots, theslotted portions carrying, pivot pins 35. Laterally spaced connecting links 36 are pivotally mounted at one end. upon the pins 35, the other ends of said links being connected by pins 37 to the lower ends of laterally spaced bell crank levers 38'which are pivotally mounted at 39 and provided with arcuate slots 40 in their shorter arms for receiving laterally presented pins 41` carried by connecting links 42. Said links 42 are pivotally mounted at their upper ends upon pivots 42 carried by the deflected bracket arms 43. The bracket arms 43 are rigidly secured `,to vertically reciprocable rods 'or plungers 44 which have their lower ends embedded in the cross heads 6. The upper ends of the rods 44 are slidably mounted in the laterally presented arms 45 of a trian 11- v larvbracket 46, said triangular bracket being provided with a boss47 which is rigidly secured to the upper lend of a power driven plunger 48 which reciprocates vertically.

Secured to the upper end of each of the rods 44 and .limiting the downward vdisplacement of said rod with respect tothe bracket arm L4 5, is a collarl 49. 'A helical'spring 50 which is interposed between each bracket arm 45 and the bracket 43, tends to retain the collar 49 in abutment with the bracket arm 45. Se-

cured to the lower' end of each of the plungers 44 by means of a screw. 51, is a cap-applying disk 52I which operates within a cylindrical chamber 53 formed within the bottom 'block or foot 10 of the hopper. Each of the tubular hoppers is provided with upwardly presented spring clips 54 for the reception of suitable vstacking receptacles 55. lAs shown in Figures 1, 3, 6 and 14, a pair of oppositely arranged arcuate straps 56 are secured tothe outerA wall of the hopper 9 by means of screws 57. A series of` screws 58, mounted in outwardly bent portions of the straps 56, serve as pivots for cap-holding levers 59 which are provided at their lower ends with cap engaging claws 60. Said levers, as shown best in Figures'll and 12, are provided at their upper ends with cam arms 61 by means of which saidcap holding levers are adapted to be moved radially inwardly l and outwardly within diagonal slots 62 (see Figures 3 and 9) for successively releasing one cap and engaging another. Movable axially on the outer wall of each of the cap hoppers are cam segments 63 which are provided with axial slots 64, through which extend screws 65 for y connecting said segments to the hopper 9.

The lower ends of spring clips 54 constitute fixed abutmcnts for limiting theupward movement of the cam segments 63 with respect to the hoppers 9. Each of the cam segments 63 is provided with an inwardly presented bevelled cam-surface 66 which is adapted to impart an inward displacement to the cam arms 6l of the cap holding levers 4, moving the claws 60 out of stack supporting position at such times as the cam segments are displaced downwardly'upon the hopper walls 9. A normal tendency to retain the cap holding arms in stack supporting position is imparted by a coil spring 67 which, as shown in Figure 8, extends around the lower end of the hopper and embraces the lower arms of the levers-59. The ends of coil spring 67 are secured by a screw 68v to the hopper wall. `Suitable means for effecting a downward displacement of thecam segments 63 at times when the cap feeding slide is in its forward position to receive a cap released from the v'lower end of the column, may be provided in the form of stops or bracket arms 69 which are secured to the cross frame or bracket 3. A cap thus deposited upon thefslide in its forward position is the retraction of said sllde from its position shown -1n Figure 7, the cap is intercepted by a dependingV rod or guard 71 which sweeps the released cap fromthe slide and permits ofthe slide, the 'laterally-spaced fingers 32. which are presented forwardly therefrom-V .yieldably held thereto by suction and during 'l prevent an undue lateral displacement of the cap while permitting said cap to drop little by little into position over the suction opening 18. As shown in Figures 9 and 10, Aa

. pair of laterally spaced spring arms 7,0 are Operation As shown in Figures 1 and 6 of the drawings, the cap-feeding table is in lowered position with the neck of a bottle presented within the opening 14. The cap-applying plunger- 44 has just completed its downward or capapplying movement. During this movement, the cap-conveying slide has been retracted and the next cap in order to be released from the stack has been swept from the slide by the depending rod 7l.' This cap is held by suction in the path ofthe slide on its next inward movement. As the cross-head 6 moves upwardly for this purpose, the cap-applying plunger is lifted while the pins at the lower ends of the connecting links are moving upwardly in the arcuate slots 40with which the short arms of the bell-crank levers 38 are provided. An inward movement of the slide follows, the detached bottom cap which is held in position by suction being picked up by said slide and presented above the mouth of the next vessel which has in the meantime reached a suitable position to receive the cap on the next downward movement of the cap-applying plunger. .During the progress of this movement ofthe capteeding slide, however, the, movable cam segments are brought into engagement with the iixed bracket arms 69 which produce an actuation of the cam-actuated cap-retaining levers, moving them to release position and permitting the column of caps to rest upon the table. At the commencement of the downward movement'of the main driving crosshead and cap-applying plunger, the cam-segments are moved away from the iiXed bracket arm and thus permit the cap-retaining levers to be drawn inwardly by the helical spring 67 into position to support all but the lowermost cap in the column. With the several parts in their relative positions shown in Figure 7, the main driving cross-head moves downwardly, the cap-feeding table being eventually arrested in its downward movement by the tixed bracket l5. The pins 41 at the lower ends of the connecting links now move downwardly in their respective arcuate slots while the cap-applying plunger begins its cap-applying movement. As soon as the lost motion between the connecting links and bell crank levers has been taken up the capfeeding slide moves to its outermost position operatin@r lower end of said hopper, said slide v in readiness for another cycle of operations.
